Recent advances in design, sensing and control have led to aerial robots that offer great promise in a range of real-world applications. However, one critical open question centres on how to improve the energetic efficiency of aerial robots so that they can be useful in practical situations. This review paper provides a survey on small-scale aerial robots (i.e. less than 1 m 2 area foot print, and less than 3 kg weight) from the point of view of energetics. The paper discusses methods to improve the efficiency of aerial vehicles, and reports on recent findings by the authors and other groups on modelling the impact of aerodynamics for the purpose of building energy-aware motion planners and controllers.

“…The electricity can then be used to charge the battery onboard the AUV. The idea is similar in concept to laser power beaming [13], but we are only interested in relatively low power transfer over very short distance underwater. We choose LED luminaire as the light source, since on average it has superior performance, in terms of efficiency and rated life time, when compared to other lighting technologies such as fluorescent and halogen.…”

This paper describes a conceptual system to assist an autonomous underwater vehicle (AUV) land on an underwater docking station, and transfer energy to the vehicle to enable underwater battery charging. The system consists of light emitting diodes (LEDs) mounted on the docking station, and optical sensors and photovoltaic (PV) cells on board the vehicle. The combination of sensors on board the AUV and the docking station LEDs will allow the vehicle to estimate the relative position of the intended docking location. Once the vehicle has landed on the docking station, the combination of the LEDs and the PV cells allows the battery on board the vehicle to be charged without any physical contact.

This paper describes the novel use of high power laser diodes for rapid delivery of power and data to wireless sensors when solar illumination is not an option and continuous point-to-point power flow is not desirable. A single high power, laser diode source can service multiple sensors, either sequentially or in parallel. Laser irradiance levels exceeding 10k suns decrease the charging time of a super-capacitor, without damage to the photovoltaic converter. Alternatively, multiple devices, connected in parallel, also reduce the charging time. We demonstrate the efficacy of the approach using four photonic power converters. Simultaneously, with delivery of power, IrDA transreceivers establish full-duplex communication between the transmitter and receiver.
